Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging jig for an outer wall member which can be mounted while lifting a plurality of outer wall members by one crane operation.

[0002]

2. Description of the Related Art The work of fixing an outer wall member to a mounting position is
Usually, each crane is hung by a crane and lifted to the target position.
The workability was poor because it was being installed.

By the way, the outer wall member P is heavy.
In addition to the C version, there is a lightweight aluminum curtain wall. Since the lifting load per sheet of this curtain wall is small, the load on the crane is small even if several curtains are simultaneously lifted.

Therefore, recently, a hanging jig has been developed in which a guide rail that can be horizontally moved by a motor is arranged inside the upper portion of a box-shaped frame, and a plurality of curtain walls are hung in a row below the guide rail. The hoisting jig is lifted by a crane and sequentially positioned at the mounting position, and then the guide rails are moved to feed the sheets one by one from the opening of the frame to fix the crane. The number of times of lifting is reduced to streamline the work.

[0005]

However, in the hanging jig of this structure, since the frame is formed in a box shape, the weight of the jig as a whole is heavy and the hanging load becomes extremely unbalanced as the number of jigs decreases. There was a problem in terms of stability, such as easy balance and difficulty in removing and fixing the curtain wall due to the inclination of the frame.

The present invention is intended to solve the above problems, and its object is to make the hanging jig itself lightweight.
Provided is a hanging jig for an outer wall member, which can stably supply a plurality of outer wall members to a mounting position even if the hanging jig is tilted.

[0007]

In order to achieve the above object, the present invention relates to an upper suspension girder suspended on a crane hook, and a lower suspension girder integrally and parallelly arranged under the upper suspension girder. A plurality of arms, one end of which is swingably hinged to the lower suspension girder, and folds via wires that are connected to the suspension girders at the tips of the arms and are parallel to each other, and that are extended from the upper suspension girder. A plurality of auxiliary beams horizontally supported in a deployable manner and a folding deploying device arranged on the upper suspension girder are provided, and an outer wall member is suspended and supported at a lower portion of each auxiliary beam. .

[0008]

With the above construction, when the upper suspension girder is lifted by the crane while the outer wall member is suspended under each auxiliary beam, the upper and lower suspension girders are lifted at an inclination according to the load balance of each outer wall member. The outer wall members are suspended and supported in a vertical state of their lower loads. At the mounting position, take out the outer wall member located on the front side in order, perform the fixing work, and wind up the wire supporting the auxiliary girder that is in an empty state, the auxiliary girder that becomes empty is folded, The next outer wall member is located at the forefront. Hereinafter, by repeatedly supplying and folding the outer wall members at the intended mounting positions one after another, a plurality of outer wall members can be fixed at a plurality of locations by one lifting operation. It should be noted that the load balance changes and the inclination angle of the suspension girder changes with each supply, but the posture of the outer wall member is corrected vertically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a hanging jig for an outer wall member according to the present invention. The hanging jig 1 is a crane hook 2.
And an upper suspension girder 3 suspended from the upper suspension girder 3 through a wire 2a, and a pair of lower columns of the upper suspension girder 3 which are vertically provided on both sides of the lower suspension girder 3, and are arranged in parallel with the upper suspension girder 3. And a lower suspension girder 5.

A plurality of pairs of arms 7 whose one ends are swingably supported via hinges 6 are provided on one side of the lower suspension girder 3, and the ends of the arms 7 are respectively arranged in order from the outside. A plurality of auxiliary beams 8 parallel to the beams 3 and 5 are connected.

A pair of hanging portions 8a of the curtain wall W are provided on the lower surface of each auxiliary beam 8, and the upper ends of the curtain walls W are suspended on the hanging portions 8a, so that the number of curtain walls W corresponding to the number of the auxiliary beams 8 is increased. Will be lifted at once.

Both ends of each auxiliary beam 8 are horizontally supported by wires 9 extended from the upper suspension girder 3 so as to be foldable and expandable.

Each wire 9 is connected to a plurality of wire winding motors 10 (folding and unfolding device) arranged on the upper suspension girder 3 via respective winding mechanisms such as reels. The auxiliary beam 8 can be folded from the illustrated horizontal state to the inverted state. Since the driving force of each motor 10 may be set to a magnitude corresponding to the weight of each curtain wall W, a lightweight and small one is used.

In the above structure, the hanging jig 1 is hung down to the slinging position in a state where each auxiliary beam 8 is expanded horizontally, and the curtain wall W is hung on each auxiliary beam 8 here. Then, as shown in FIG. 2 (a), a crane is used to perform lifting work. While the hoisting girders 3 and 5 are hoisted at an angle of inclination according to the load distribution of the curtain wall W at the time of lifting, each curtain wall W itself is supported in a vertical state.

At the first mounting position A, the curtain wall W positioned in the front row is supplied to the mounting position A. At this time, the height adjustment and the approach adjustment are performed by the crane, but the fine adjustment of the vertical and approach distances beyond the adjustment range is performed by the forward and reverse rotations of the motor 10 of the auxiliary beam 8 in the front row. Thus, the auxiliary beam 8 in the front row moves up and down while approaching and separating, and the mounting position is adjusted.

When the attachment of the frontmost curtain wall W is completed and the sling is removed, the slanting angles of the suspension girders 3 and 5 become shallower according to the variation of the load distribution, but the remaining curtain walls W automatically. Vertically.

Thereafter, as shown in FIG. 2B, when the motor 10 is driven to fold the auxiliary beam 8 in the front row, the curtain wall W in the next row can be attached and the crane is laterally moved. To the next mounting position, and the mounting work can be performed in the same manner as described above. By successively repeating the movement and the mounting work, a plurality of curtain walls W can be mounted by one lifting operation. Can be done.

Although the auxiliary beam 8 and the tilting mechanism thereof are arranged only on one side of the suspension girders 3 and 5 in the embodiment, they may be arranged on both sides.

In this case, the load distribution fluctuates extremely when the curtain wall W is removed only on one side. Therefore, a turning control mechanism such as a gyro is provided. By 180 ° to remove the curtain wall W on the other side alternately.

In the above embodiment, the wire winding motor is used as the folding and unfolding device, but it may be replaced by a hydraulic jack.

[0021]

As described above in detail with reference to the embodiments, in the hanging jig for the outer wall member according to the present invention, the upper suspension girder is hung with the outer wall member suspended under the auxiliary beams. When lifted by, the upper and lower suspension girders are lifted at an inclination according to the load balance of each outer wall member, and each outer wall member is suspended and supported in the vertical state of the lower load thereof, so that the structure can be simple and lightweight.

At the mounting position, the outer wall members located on the front side are sequentially taken out and fixed, and the wire supporting the vacant auxiliary girder is wound up to fold the vacant auxiliary girder. In rare cases, since the next outer wall member is located at the forefront, the outer wall members can be sequentially attached to the intended attachment positions.
It should be noted that although the load balance changes with each supply, and the slant angle of the suspension girder also changes, the posture of the outer wall member is corrected vertically, so that there is an advantage in that the balance fluctuation does not hinder the mounting.
